AI Technical Summary

Benefits of technology

The composition provides excellent softening effects while ensuring satisfactory biodegradability, reducing environmental impact, and maintaining storage stability.

Problems solved by technology

However, the quaternary ammonium salt described above suffers from the problem that, when residues thereof after a treatment are discharged into the environment, such as a river, most of them will accumulate and are not biodegradable.
Although the biodegradability of these products is better as compared with those products having the quaternary ammonium salt described above, the improved products still have insufficient softening effects.

examples 1-1 to 1-6

[0043](A-1) a reacted product of diethanol amine with a hardened tallow fatty acid at the molar ratio of 1:2 as the component (A), (B-1) octadecyl trimethyl ammonium chloride as the component (B) and further (N-1) an adduct with 20 mole of ethylene oxide to dodecyl alcohol as a nonionic compound other than the component (A) were used. They were dispersed in water in amounts shown in Table 1 to prepare each of the softener compositions. This composition was evaluated for a softening effect in the following manner. The results are shown in Table 2.

[0044]① A mixture of the components (A) and (B) and the other component was molten and added dropwise to water under stirring to prepare each of dispersions having the concentration shown in Table 1. As a comparative control sample, a 5% dispersion of N-methyl-N,N-bis(tallow alkanoyloxyethyl)-N-(2-hydroxyethyl) ammonium methyl sulfate was prepared in the same manner as above.

[0051]The components (A) and (B) mentioned in Table 1 were dispersed in water in amounts shown in Table 1 and then an evaluation for a softening effect was carried out in the same manner as in Example 1. The results are shown in Table 2.

examples 15-1 to 15-7

[0052]Each of softener compositions was obtained by the same manner as in Example 1 except that the above-mentioned (A-1) as the component (A), (B-7) N-(3-hardened tallow alkanoyl aminopropyl)-N,N-dimethylamine as the component (B) were used and that they were dispersed in water in amounts shown in Table 3 and further hydrochloric acid was added dropwise thereto to adjust pH to 2.5. The composition was evaluated for a softening effect in the same manner as in Example 1. The results are shown in Table 4.

Abstract

The present invention provides a softener composition which contains a softening base having an excellent softening effect and satisfactory biodegradability. That is, the present invention provides the softener composition which comprises (A) a nonionic compound which has at least one C5-36 alkyl or alkenyl group and an amide bond but contains no dissociative group of amino or carboxyl group; and (B) at least one member selected among (B-α) cationic or ampholytic surfactants having one C5-36 alkyl or alkenyl group or one optionally substituted aryl group and (B-β) amino compounds having at least one C5-36 alkyl or alkenyl group and salts of the compounds.

Description

[0001]This application is a divisional of Application No. Ser. 09 / 700,498 filed on Dec. 29, 2000, now U.S. Pat. No. 6,541,444 and for which priority is claimed under 35 U.S.C. § 120. Application Ser. No. 09 / 700,498 is the national phase of PCT International Application No. PCT / JP99 / 02619 filed on May 19, 1999 under 35 U.S.C. § 371. This application also claims priority of Application Nos. 10-138701 and 10-162329 filed in Japan on May 20, 1998 and Jun. 10, 1998, respectively, under 35 U.S.C. § 119. The entire contents of each of the above-identified applications are hereby incorporated by reference.TECHNICAL FIELD[0002]The present invention relates to a softener composition.Background Art[0003]Most of the commercially available merchandise as a softener composition for fibers are compositions comprising a quaternary ammonium salt containing two long-chain alkyl groups in one molecule, typically having a di(long chain alkyl) dimethyl ammonium chloride.[0004]However, the quaternary amm...
